72 Chapter 3 Managing the network access devices
320818-A
Before you begin
In Trusted Computing Group (TCG) terminology, the edge switches in a Nortel
SNA solution function as the Policy Enforcement Point. In this document, the
term network access device is used to refer to the edge switch once it is configured
for the Nortel SNA network.
The following edge switches can function as network access devices in the Nortel
SNA solution:
• Ethernet Routing Switch 8300
• Ethernet Routing Switch 5510, 5520, and 5530
Before you can configure the edge switches as network access devices in the
Nortel SNAS 4050 domain, you must complete the following:
• Create the domain, if applicable. If you ran the quick setup wizard during
initial setup, Domain 1 has been created. For more information about creating
a domain, see “Configuring the domain” on page 117.
• Configure the edge switches for Nortel SNA (see “Nortel SNAS 4050
configuration roadmap”, step 4 on page 45). For detailed information about
configuring the edge switches for Nortel SNA, see Release Notes for the
Ethernet Routing Switch 8300, Software Release 2.2.8 (316811-E) or Release
Notes for Nortel Ethernet Routing Switch 5500 Series, Software Release
4.3 (217468-B).
For secure communication between the Nortel SNAS 4050 and the network access
device, each must have knowledge of the other’s public SSH key. After you have
added the network access device to the Nortel SNAS 4050 domain, you must
exchange the necessary SSH keys (see “Managing SSH keys using the CLI” on
page 84 or “Managing SSH keys using the SREM” on page 102).
